I have encountered an issue on the portal frame model on SAP2000 when I use diaphragm to compute the wind load automatically in different wind directions. The error is as below when run the analysis, stating that numerical problems unencountered during equation assembly. I have also attached the Sap2000 model for reference https://files.engineering.com/getfile.aspx?folder=33daa0a9-3101-41e0-9252-c18b38a568a3&file=SAP2000_Analysis_error.JPG https://files.engineering.com/getfile.aspx?folder=97899e91-65b6-4f0c-b6bb-0b7b5cdc7651&file=Trial_model.sdb Could someone help me out Thank you very muchhttps://files.engineering.com/getfile.aspx?folder=97899e91-65b6-4f0c-b6bb-0b7b5cdc7651&file=Trial_model.sdb ; https://files.engineering.com/getfile.aspx?folder=33daa0a9-3101-41e0-9252-c18b38a568a3&file=SAP2000_Analysis_error.JPG
